In a small pot combine the hot water and the bath soap. Once the soap has melted, add the glycerin and the eau de cologne to the mixture. In a separate container mix the freshly squeezed lemon juice and the warm water and shake or stir. Apply the soap and glycerin mixture to damp hair and massage the scalp creating a nice lather. Rinse with the lemon and water mixture to seal the hair. Dry and style as usual.
